When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

Let's build a Bitly Clone!

Bitly is a url shortening service. Building a url shortener is a common interview question / take home project, because it's a minimal project that involves many aspects of web development. Build a website that allows you to submit a link, then gives you a new, hopefully shorter url to use for that link.

Advice and motivation

Typically at Hacker School understanding is emphasized over ability to throw things together - this is an exercise in the latter. It's also practice reading documentation to figure out how to do things quickly, and a guided way to gain exposure to web development concepts that you might research more after this sprint today. It reminds me (in good and bad ways) of a hackathon.

How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: [email protected]:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

	# Pick and choose what you want, as all models don't NEED to be tested at this depth.

	# I'm always eager to hear new tips & suggestions as I'm still new to testing,

	Introduction:

	This coding challenge is designed for you to show off your skills to the 3Play Media Developer team. You
	should have the following challenge completed by the time you come in for your in-person interview so we
	can take a look at it together. While all of the basic requirements of this project should be met, you're
	encouraged to make this project your own and implement any additional features that you see fit.

	Feel free to ask whatever questions, use whatever resources and provide whatever documentation
	you'd like during the completion of this project.
